To all whom it may concern:

Be it known that '1, WILLIAM A. ZEIDLER, a citizen of the United States,and a resident of New York city, in the county of New York and State ofNew York, have invented certain new and useful Improvements in Machinesfor Folding and Shaping Turn- Down Collars, of which the following is aspecification.

The invention relates to improvements-in machines for folding andshaping turn-down collars and similar articles; and it consists in thenovel features and combinations of parts hereinafter described andparticularly pointed out in the claims.

The object of the invention is to provide a machine which will uniformlyand prop erly fold and shape the collars in a manner which will renderthe latter entirely satis factory to the wearer. and not injure thecollar. j

The presentinvention comprises certain improvements, hereinafterdescribed, upon the machines made the subject of Letters Patent No.64:2,660granted February 6,1900

to William A. Z'eidler and No. 646,784

granted April 3, 1900 to William A. Zeidler, and said invention will befully understood from the detailed description hereinafter presented,reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation, partly broken away and partly in section,of a machine constructed in accordance with and embodying the invention;Fig. 2 is a top view of a part of'one end of the machine, Fig. 5

being taken from the rear side of the ma thereof; Fig. 6 is a detachedtop viewof the receptacle for receiving or into which are fed thefinished collars and from which said collars are from time to time, asrequired, removed by hand, and Fig. 7 is adetail of a same, thesuperposed receptacle to receive chine and Figs. 1 and' i from the frontside portion of the mechanism for feeding the folded collar to theshaper.

In the drawings,10 designates the bedof the machine, and 11, 12 and 13denote respectively three standards upon said bed plate and whichsupportall of the operative mechanism of the machine. The maindrivingshaft 1 1- is mounted in the standards 12,

.13 and is provided witha loose pulley l5 and fast pulley 16, as usual,whereby said shaft and the parts'connected with it may be driven bypower. WVithin a sleeve 17 supported by arms 18 from the standard 11 ismounted an auxiliary driving shaft 19, upon the front end of which issecured a conical shaping disk 20 of the character described in myaforesaid Letters Patent. The

shaft 19 is driven from the shaft 14 through i a series of gear wheels21,v 22 and 23 (Figs. .1 and 2), the gear wheel 21 being rigidon 75.'the shaft 14, the gear wheel 23 rigid on the shaft 19 and the gearwheel22beingsimply an intermediate gear supported on a stud .24:extending from an arm forming a part of the standard 12 (Fig. 2).

The conical shaping disk 20 has imparted to it during the operation ofthe machine a rotary motion but is otherwise rigidly held, and'said disk20 has its conical interior extended outwardly from the end of the 5shaft 19, whereby the interior chamber of said disk is not occupied byany portion of the shaft and is exposed so that the collars mayreadilypass through the same and be observed by the operator.

The conical disk 20 cooperates with a rotary ironing and shaping roller25 having an annular groove 26 into which the edge I of the disk'20enters. The ironing roller '25 is secured upon the upper end of a shaft27 which extends upwardly and outwardly and is adapted to be driven fromthe shaft 19 through the gear wheels 28, '29, 30, 31, (Fig. 1) and aninclined shaft 32, the gear wheels 29, 30 being on the shaft 32, thegear 101 V wheel 28 on the shaft 19 and the gear wheel 31 on the shaft27. The disk 20 and ironing roller 25 rotate toward'each other and thefolded collar 33 is fed inbetween the adjoining portions of said diskand roller, as

shown in Fig. l, the inner fold or section of folded edge of-thecollar'being against the edge of said disk and within the groove 26 ofsaid roller 25.

The ironing roller 25 should have a yielding relation to the edge of theshaping disk 20 because of the varying thicknesses of collars and inorder to enable said roller to properly engage the folded edge of thecollar without injuring the same, and to provide for this condition Imount the shaft 27 within a sleeve 34 (Fig. 1) which is pivotallysupported upon the inner ends of screws 35 (Fig. 2) which enter arms 36extending forwardly and downwardly from and are integral with thestandard frame 11. The shaft 27 may, therefore, have a limited tiltingor oscillatory motion imparted to it and thereby the ironing roller 25may have its relation to the disk 20 regulated at will. If leftunrestrained the roller 25 would have a tendency to fall away from thedisk 20 so far as the gear wheels 31, 30 would permit, and to preventany undue approach of the roller 25 toward the disk 20 I provide anadjustable stop 37 which is supported from the main standard or frame 11andis in line with the sleeve 34. It is desirable that the roller 25should remain in near relation to the disk 20 but it is not desirable,in many instances, that said roller should press with great forcedirectly against said disk, for under suchcondition the collar passingthrough the machine might be in jured at its folded edge. The roller 25is given a yielding pressure toward the disk 20 by means of a weight 38,crank arm or beam 39 and rod 40, the latter at its lower end beingpivotally secured to the sleeve 34 and at its upper end having athreaded section 41 which passes loosely through a stud 42 extendingupwardly and forwardly from the hub 43 of the crank arm 39. The forwardend of the crank arm 39 extends upwardly, as shown in Fig. 1, andterminates in the aforesaid hub 43, through which a pivot-screw 143passes, this screw constituting the pivotal point for said arm. Theweight of the roller 25 and the freedom of play between the gear wheels31, 30 enables said roller, through the rod 40, to normally hang fromthe stud 42 of the crank arm 39, and the roller 25 is restrained fromfalling unduly away from the disk 20 by the fact that the head of theadjustable section 41 of the rod 40 has a bearing against the upper sideof said stud 42. When a collar is inserted between the disk 20 andironing roller 25 it is fed inwardly by the rotary action of said diskand roller and due to the thickness of the collar the roller 25 isforced downwardly in a direction from the disk 20, and this downwardmovement of the roller 25 is resisted by the weight 38. The weight 38,crank arm 39 and stud 42 hold the roller 25 in a proper initial relationto the disk 20, but when a collar is inserted between said disk androller, the thickness of the collar presses the roller 25 slightlydownwardly, and said roller 25 when thus pressed downwardly operatesthrough the rod 40, stud 42 and arm 39 to slightly elevate the weight38, whereby the latter is enabled to cause the roller 25 to yieldinglypress against the collar. The adjustable stop 37 prevents the weight 38from unduly elevating the roller 25 toward the disk 20, and the forcethe weight 38 may exert against the roller 25 may be varied by adjustingsaid weight along the arm or beam 39, the weight 38 exerting thegreatest force when it is at the outer or left hand end of said arm orbeam 39. The adjustable section 41 at the upper end of the rod 40 has atits outer end a knob or enlargement which pulls against the stud 42 whenthe ironing roller 25 is pressed downwardly, and the said section 41 ismade adjustable so that it may be passed through the stud 42 and screwedinto the end of the rod 40 and also so that it may be utilized toregulate the length of said rod 40.

The stud 42 represents a short lever and the arm or beam 39 a longlever, which is substantially horizontally disposed at the front side ofthe machine, and the weight 38 is hung by loops 45 from said arm or beam39. lVith a reasonably light weighthung from the arm 39 the ironingroller 25 may be caused to press with considerable force against thecollar passing through the machine, this being due to the leverageofsaid arm 39. The arm 39 and weight 38 are at the front of the machinewhere the operator is located to feed in the collars, and hence saidweight is conveniently disposed for ready adjustment.

When the machine is in use the conical disk 20 will be heated by a flamefrom a gas burner 46 and the ironing roller 25 will be heated by flamesfrom gas burners 47, which burners 46, 47, are, as shown in Fig. 3,con-.

nected with the gas supply pipe 48 supported in the front standard 13 ofthe machine. The front standard 13 is formed with an upwardly andinwardly inclined head 49 from which, by means of an arm 50, issupported a curved guiding and shaping plate 51 which lies within thelower portion of the conical disk 20 and is separated from the innersurface of said disk to a sutficient extent to enable the inner fold ofa collar to pass between it and said surface of said disk. The plate 51compels the inner fold of the collar to travel close against the innersurface of the disk 20, but said plate is free of said disk andconstitutes the inner guide for the collar.

At the outer side of the lower portion of the disk 20 is arranged acurved plate guide and shaper 52 which is supported by an arm 53, Fig.5, from a portion of the standsmall angle-plate 55 to a portion of thehead 49 (Fig. 5). The plate 52'not only directs the fold of the collarto position in between the disk 20 and roller 25 but compels the outersection of the collar to travel close against the exterior wall of thedisk20, the plates 51 and 52 cooperating to compel the two folded partsof the collar while traveling through the machine, to move close againstand follow the curvature of the inner and outer walls of said disk.Beyond the disk 20 the plate 52 is provided with an inner curved plate56 (Fig. 4), and between the plates 56, 52 is provided an upwardlyinclined floor 57 up which the collar traveling through the machine iscompelled to pass, the folded edge of the collar riding on said floor57, while the two folds of the collar are confined between said plates56, 52, both of which are correspondingly curved whereby they areenabled to retain the collar in a curved condition. The curvature of theplates 56, 52 is such as topenable the collar to become partly shaped,but it is on too great an arc to effect the final shaping of the collar,and hence upon the upper portion of the head 49 I provide additionalmeans for receiving the collar from i the plates 56, 52 and completingthe shaping thereof.

The plates 56, 52 and floor 57 direct the collar upwardly and deliver itto a point' between a rubber or frictional feed roller 58 and a polishedrounded surface 59 (Fig. 5) on the rear side of the standard 60 whichinclines upwardly and inwardly from the upper end of the head 49, thefront wall of said standard being shown in Fig. 4 and the rear wallthereof being curved to cooperate with the roller 58 in efiecting theonward travel of the collar. r

The rounded surface 59 on the post or standard 60 does not extend to thelower edge of the roller 58, a recess 100 being formed in said standardopposite to the lower portion of said roller, as shown in Fig. 7, thisrecess beingto enable the feeding of the collar between the roller andstandard without said parts creating any material pressure against. thefolded edge of the collar, this being an important feature since therebythe folded edge ofthe collar is left with correctly rounded surfaces andthe collar does not become broken at its folded edge, as is the case inmachines which during the feeding of collars pinch the folded edge ofsame. The inner fold of the collar moves against the standard 60' and--the outer fold thereof is engaged bythe rubber roller 58, and thelatter extends across the full width of the outer fold "of the collar soas to eflect-ually feed and not leave any mark on the same, as might bethe case if the lower end of the roller 58 pressed against the outerfold of the collar along a line above the edge thereof.

. The plates 56, 52 terminate at the space between the roller 58 andcurved face 59 of the standard 60, and immediately beyond the contactsurfaces of the roller 58 and standard 60 I provide a plate guide andshaper 61 which is somewhat of conical shape'and takes a spiral courseupwardly and around said standard 60. The guide 61 is supported from thehead 49 by means of a rod 62, and along its inner lower spiral edge, theguide 61 is formed with a floor 63 which receives the collars from theroller 58 and directs them upwardly along a spiral course, the collarsupon leaving the roller 58 traveling around within the guide and shaper61 toward the'front side of the machine and then around toward the rearside thereof on an upward spiral course and finally emerging from theguide 61 at a point between the upper rear curved side of the standard60 and a smalloblique rubber wheel 64 (Figs. 2 and 5), whence thecollars,

pass into the'superposed receptacle 65, which is fastened by screws uponthe upper end of the standard 60, the screw holes for the screws beingrepresented in Figs. 2 and 6.

The guide 61 is of conical spiral nature and within it theshaping of thecollar into its proper curved form for use is completed, the collarafter leaving the plates 56, '52 being closely coiled on a spiral linewithin the guide 61 and held therein, during the period of travel, asuflicient length of time to receive a proper set after which thecollars are allowed -to spread somewhat ;'within the receptacle 65, fromwhich they are, from time to time, removed by hand.

The roller 58 is mounted upon a shaft 66 confined within a sleeve 67which is pivotally held by screws 68 in a fork 69 constituting a part ofthe head 49, whereby said roller 58 is enabled to yieldoutwardly fromthe standard 60 during the travel of the collars between said roller andstandard. A coiled spring 70 (Figs. 2 and 3) is provided to pressagainst the sleeve 67 for the purpose of imparting to the roller 58 ayielding or spring pressure against the collars passing between it andthe standard 60, said spring 70 being held ina suitable frame 7i andbeing adjustable with respect to its tension-by meansof a screw 72. Theroller 58 and its shaft 66 receive their rotary motion from the maindriving shaft 1 1 through the beveled gear wheel 73 secured on saidshaft 14 and the intermeshing beveled gear wheel 74 secured on the lowerend of said shaft 66. During the operation of the machine the feed andpressure wheel 58 therefore has a rotary motion imparted to it and itpresses the folded collars against the standard 60 and compels thecollars to take a spiral course upwardly through the guide and shaper61.

The wheel 64 will preferably be of rubber or other frictional materialand it has a ro tary motion imparted to it from the shaft of the roller58, the shaft of said roller and the shaft of said wheel being connectedby a universal joint connection 75 (Fig. 3), whereby rotary motion maybe imparted to the wheel 64 without regard to the .yielding movements ofthe roller 58 and its shaft. The wheel at is carried upon the upper endof an arm 76 (Figs. 2, 3, 5) which is somewhat yielding and intended topress, with a spring pressure, the roller 64 against the rear curvedside of the upper end of the standard 60.

I have hereinbefore described all of the structural features of themachine with the exception of the superposed receptacle 65, which, ashereinbefore explained, receives the completed collars from the guideand shaper 61 and is fastened upon the upper end of the standard 60.

The receptacle 65 is provided with a downwardly extending lip 77 (Fig.6) which projects downwardly into approximately near relation to thedischarge sides of the wheel 64 and standard 60 (Figs. 3, a, 5), anddirects the collars leaving said standard and wheel upwardly into themain compartmentof said receptacle, the floor of said receptacle beingslotted, as at 78, (Fig. 6) to permit the ascent of the collars. Thereceptacle 65 comprises the aforesaid lip 77, floor 79, circular rim 80,a partial cover 81 along said rim and a guiding flange 82 whichconstitutes a portion of the rim 80 but as shown in Fig. 6, is deflectedinwardly over the guiding lip 77 to compel the collars to travel alongthe inner wall of said rim 80. Beyond the general outline of the rim 80the floor 7 9 is extended outwardly, as at 83 (Fig. 6), along oneportion of which is provided a vertical rim or wall 84 over whoseterminus is a cover 85, the latter being secured to the rims 84 and 80.The collars fed into the receptacle 65 travel along the inner wall ofthe rim 80 in the direction of the arrows (Fig. 6) and will gatherwithin said receptacle along the said wall, the collars finally lyingone against the other within that portion of the receptacle 65represented at the left hand side of Fig. 6, the outer ends of thecollars passing upon the extension 83 of the floor of the receptacle andfinally entering the chamber below the covering plate 85. The rim 84:and cover 85 prevent the collars from discharging from the receptacle,and after a suitable number of collars have gathered within thereceptacle, either regularly or irregularly disposed therein, they areremoved by hand. The circular rim 80 of the receptacle 65 prevents thespreading out of the collars to any undue extent, and the collars whenremoved from the receptacle are found to be properly ironed, shaped andset and ready for use.

The operation of the machine will be largely understood from thedescription hereinbefore presented and hence only brief furtherexplanation is required. The disk 20 and its shaft 19 are driven fromthe main driving shaft 1a through the series of gear wheels 21, 22, 23,and the ironing roller 25 is driven from the shaft 19 through the gearwheels 28, 29, 30, 31 and shafts 32, 27. The roller 58 is driven fromthe shaft lat through the gear wheels 73, 74, and the feed wheel 6%receives its motion from the shaft of the rubber roller 58. The collarsare fed to the disk 20 and roller 25 by hand and with the aid of theguiding plate 52, as indicated by dotted lines in Fig. 2. The fold ofthe collar passes between the edge of the disk 20 and the surface of thegroove 26 in the roller 25, while the inner fold or section of thecollar is delivered between the inner surface of the disk 20 and theadjacent surface of the plate 51, and the outer fold or section of thecollar passes between the outer surface of said disk and the inneradjacent surface of said plate 52. The disk 20 and roller 25 will gripthe collar and draw the same into the machine and compel the collar totravel along the plate 52 and up the inclined floor 57 thereof. Theplates 52, 56 and floor 57 deliver the folded collar, ironed along itsfolded edge, to the roller 58, which due to its rotation and thepressure exerted by it against the collar between it and the standard60, draws the collar upwardly from the guides 52, 56 and compels thecollar to travel upwardly along the spiral floor 63 of the guide 61,wherein the collar is properly shaped. Finally as the collar reaches theupper end of the floor 63 and guide 61 it is engaged by the rubber wheel64 which cotiperating with the curved rear surface of the standard 60,compels the collar to ride up the lip 77 of the receptaclev 65 and enterthe latter, the treatment of the collar then having been completed. Iindicate in Fig. t by arrows the path taken by the collar on its passagefrom the ironing roller 25 and disk 20 to'thereceptacle 65, showing onlya portion of the collar in Fig. 4 so as not to obscure therepresentation of the several parts of the machine.

The special features constituting the invention relate to the generalarrangement of the parts of the machine, the special 06- operativearrangement of the disk 20 and roller 25, the means for enabling theroller 25 to have a. yielding pressure toward the disk 20 and the guidesfor properly directing and shaping the collar after it leaves thedisk'QOand roller 25.
